Dual citizenship - South Africa/UK

Hi there
I have acquired my British passport about a month ago. I also have a valid SA passport, and have lived in SA my entire life. Does the acquiring of my British passport automatically take away my SA citizenship? Or can I still leave and enter SA with my SA passport and use my British passport elsewhere?
Thank you
Rabie

Hi there,can someone help please..I am not sure about certain questions on the bi-1664 form for retention of SA citizenship, the 6th point ask your postal address, is that my postal address in south africa or my postal address here in the uk? And then point 9. Particulars of foreign citizenship to be accuired,COUNTRY?, HOW TO BE ACCUIRED? What do i write there?
